Downloads the appropriate gnparser executable for your platform and
tries to copy it to a system directory so rgnparser can run the
gnparser command.
Arguments
- version
The gnparser version number, e.g.,
1.0.0; the defaultlatestmeans the latest version (fetched from GitHub releases). Alternatively, this argument can take a file path of the zip archive or tarball of gnparser that has already been downloaded from GitHub, in which case it will not be downloaded again. The minimum version isv1.0.0because gnparser v1 introduced breaking changes - and we don't support older versions of gnparser here.- force
Whether to install gnparser even if it has already been installed. This may be useful when upgrading gnparser.
Details
This function tries to install gnparser to Sys.getenv('APPDATA') on
Windows, ~/Library/Application Support on macOS, and ~/bin/ on
other platforms (such as Linux). If these directories are not writable, the
package directory gnparser of rgnparser will be used. If it
still fails, you have to install gnparser by yourself and make sure it can
be found via the environment variable PATH.
This is just a helper function and may fail to choose the correct gnparser executable for your operating system, especially if you are not on Windows or Mac or a major Linux distribution. When in doubt, read the gnparser documentation and install it yourself: https://github.com/gnames/gnparser#installation
